効果と用途

The main reason for AEROSIL® in gel coats, lamination resins and bonding pastes is the thickening and thixotropic effect.

Furthermore in gel coats, applied by airless spray guns, SIPERNAT in gel coats, applied by airless spray guns, SIPERNAT® precipitated silica is used in combination with AEROSIL® fumed silica to control and reduce porosity, caused by air entrapment of the spray process.

SIPERNAT® FPS-5, for example, is a high purity precipitated silica that can be utilized in dark colored gel coats to provide porosity reduction and improved leveling with no negative effects on blush resistance.
